Manufacturing large scale metal laminated object parts

Abstract

Methods and apparatus for the manufacture of laminated metal parts having external dimensions exceeding 0.5 m in length, 0.5 m in width, and 0.1 m in height. Some embodiments include methods to apply force evenly to a workpiece via multiple rams and feature stiffened platens comprised of multiple alloys. Some embodiments include modifications to the workpiece itself, including designs for a temporary vacuum or controlled gas chamber constructed around the workpiece. Some embodiments include modifications to the workpiece and the support structures surrounding the part which direct force during bonding to the part. Control systems may be employed to coordinate the operation of the cylinders with heating, cooling, and pumping operations. Finally, some embodiments include alternative heating systems such as induction or joule heating.
